The Blancpain Villeret Ref. 6639A presents a complete calendar complication—a practical display of date, day of week, and month—complemented by moon phases in an elegant red gold case. The changing face of the moon reproduced on the dial adds a poetic dimension to this sophisticated timepiece.
The complete calendar is a more practical complication than perpetual, requiring manual adjustment only once per month. Convenient under-lug correctors simplify adjustment without unsightly case-side pushers. The automatic Calibre 6639 delivers an impressive 192-hour power reserve—a full 8 days. Water resistant to 3 bar (30 meters). Unworn with complete documentation, this exceptional timepiece represents an investment in practical classical watchmaking excellence.
